India to buy 5,000 ‘filtrerete’ air purifiers

India is set to purchase 5,500 of the world’s most advanced “filtrea” air purifying plants and will use the machines in its air purification facilities, the government said on Friday.

The government will also install more than 3,000 “fritrerete” air filters at all Indian airports to improve air quality, the country’s National Green Tribunal (NGT) said in its final order.

The tribunal had earlier ordered the government to supply the machines at an affordable cost to all domestic airports by April 31, 2018.

The order was made on a plea by Airports Authority of India (AAI), the countrys main operator of airports, which has been unable to find suitable buyers for the machines.

It said the government was also to procure 50,000 of the machines by October 2018 to replace the existing ones and install them in domestic airports.

The NGT said the machines were used for “preventing harmful odours and pollutants” in air, water and land in the country.

“The NPTT was also directed to procure the equipment for purifying coal air at all international airports, including Indian ones, as well as domestic air purifications,” the order said.
